How to distinguish the quality of ASA material sealing waterproof cap
Smell
- Smell: A good ASA sealing waterproof cap usually has no irritating smell or only a slight normal smell. If there is a pungent and unpleasant smell, it is likely that inferior additives have been added or there are quality problems in the production process
Observe the appearance carefully
- Color: The color of high-quality ASA sealing waterproof caps is uniform and consistent, without obvious color difference, color spots or discoloration. If the color is uneven, there may be problems such as unstable quality or uneven material mixing during the production process.
- Surface: The surface should be smooth and flat, without defects such as bubbles, cracks, lack of glue, and flash. These defects will affect the sealing performance and aesthetics of the waterproof cap, and may also cause problems such as leakage during use
- Specifications: The size should comply with the product design requirements and relevant standards. Use calipers and other measuring tools to measure its key dimensions such as diameter and thickness. The error should be within the allowable range, otherwise it may not fit closely with the corresponding pipes or equipment, affecting the sealing effect.
- Shape: The shape is regular, without deformation, distortion, etc. Deformed waterproof caps may not be installed correctly and play a good sealing role.
Brand and manufacturer
- Reputation: Choose products produced by well-known brands and manufacturers with good reputations. You can learn about the reputation and product quality of brands and manufacturers through online reviews and industry recommendations.
- Qualifications: Check the manufacturer's production qualifications, quality certification and other relevant certificates, such as ISO 9001 quality management system certification, etc. The quality of products produced by manufacturers with complete qualification certificates is more guaranteed
